TWO APPROACHES TO A PORTABLE COLOR -MEASURING SYSTEM.

Abstract

Two approaches to color measurement are presented, the spectrophotometer and the reflectometer. Descriptions are given of two portable instruments, one of each type. The first instrument was built using a flashlight lamp as light source, a wedge interference filter as monochrometer, and a cadmium sulphide photoresistor as a detector. The second instrument was built with three filters which provided the tristimulus curves of the CIE standard observer, a flashlight lamp, and three barrier layer cells as detectors. (Author)
